From mboxrd@z Thu Jan 1 00:00:00 1970 From: Adam Ford Subject: [PATCH V4 1/3] drm/panel: simple: Add Logic PD Type 28 display support Date: Tue, 1 Oct 2019 18:39:18 -0500 Message-ID: <20191001233923.16514-1-aford173@gmail.com> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: dri-devel@lists.freedesktop.org Cc: linux-omap@vger.kernel.org, adam.ford@logicpd.com, Adam Ford , Thierry Reding , Sam Ravnborg , David Airlie , Daniel Vetter , Rob Herring , Mark Rutland , devicetree@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: devicetree@vger.kernel.org Previously, there was an omap panel-dpi driver that would read generic timings from the device tree and set the display timing accordingly. This driver was removed so the screen no longer functions. This patch modifies the panel-simple file to setup the timings to the same values previously used.
